In this episode our heroes improvise a couple of phaser weapons. When Tom and B'Elanna hide out in the Argala habitat, B'Elanna announces that they might get one more shot out of the weapon. A minute later one of the pursuing Nyrians collapses due to the cold, and she shoots another. Although both Nyrians are armed, neither Tom nor B'Elanna bother to pick up their weapons - instead they just run off with their own now non-functional weapon.

Factoid :

The 148 crew count we got last episode is confirmed in this one.

Plotline

When an alien appears on board Voyager at the same moment that Kes vanishes, he professes total innocence and surprise. Astoundingly, Janeway believes him even when more and more such swaps take place. Eventually the entire crew is gone, and Voyager is in alien hands.
